Speciication of Letters Patent. Y.j'ttlli'gglA Aug, 191S Appiieaon' ined March 7, 191.7.- seriairrc. 153,149.

To all whom it may concern Beit knownthatt I,- FRANNLIN F.. LEY, citizen of the United States, residing at Chicago, in thecou'nty of COOk'a-nd State of Illinois, have invented a certain new and useful VImprovement in Measuring Devices,- of which the following is ya, full, clear, concise, and enact description.-

My invention relates to measuring devices and is of particular service for supplying subdivided nfiaterial to apparatus' that is to be coated with such material.y

In apparatus of this character a receptacle is employed for containing the'objeots to be coated and air, laden with the subdivided? material, isdrawn' or forced past the vobject being coated,` the subdivided material being caught upon the Object that is coated with Wet sizing' or other adhesive IThis apparatus is frequently used for Coating metal objects,1 such as bedstead parts, Withbronze powder.' Y

It is the general object of my'present invention to provide improvedmeans whereby measured quantities -of V'the subdivided material maybe introduced into the receptacle. One feature of niyinventiorr resides in thel employnre'ntof al pipe having a longitudinal diaphragm or partition therein that divides the interior of the pipe into two bores or passageways.- Thcr'e'is al valve provided in conjunction with .one of these passagew'ays whereby such passageway may be opened or closed to prevent or permit the passage' of material thereirito. This' pipe, which communicates with the interior of the receptacle, tlrus has its holding capacityv ad# justable to enable it to -ineasure different quantities of the powder or. subdivided material to surit the amount thereoft-hat is` required in a given Coat-ingOperation.'

In accordance with another feature of my invention this pipe, with or without the aforesaid partition and valve, is provided at its ends with two cutoff valves each having a hole adapted for registry With the' pipe. Thesetwo cut-off valves are desirably iXe/d with Arespect-to eachother and the holes therein; are offset so that but one valve opening is in communication' with the pipe at a time. By this arrangement a hopper may be located a'b'ove the' pipe in which hopper a reserve; quantity of the subdivided material may be' disposed and from which only a measured quantity thereof may be supplied BRAD# tothe receptaclesince the cutoff valve that is adjacent the hopper is cflosed'before and while the other cutoff valve that controls ald/-y mission to the receptacle is opened.-

I also desirably provide a second pipe 'whichY is a continuation of the first and is interposed betweenk the same and the retzenY tacle; The end of this additional pipe which is nearer the receptacle is provided with a third cutoff valve that is in fixed relationjvith theot'her two cutoff valves and is desirably so related thereto that its pipe will be open into the receptacle whenthis pipeis cut off from the other pipe whereby the measured quantity ofpowder previously admitted` to the additional pipe maybe dis# chargedinto the receptacle Without permitting any of the air to escape through thepipes to'carr'y the powder or' subdivided ina-I terial tov-the exterior of the receptacle.,

I will explain my invention mor'effully'V by referenceto the' accompanying' drawings showing the preferred embodiment .thereof and-rn which F ligure I 1s a view illustrating apparatus of the character described equipped with the device of my invention; Fig. is a view on line 2;-2 or Fig. 3, on a smaller scale; Fig. 3 is a View on line 3;-3 of Fit-g2; Figs; d and 5* are views similar' to Fig. 2 but on a larger" scale showing? different adjiistnfrents; Fig. 6 is a vi-evv on line 646 of 4; Fig. 7 isa View Online 7;? ofV 5; and Figu is a. View on line' SS of Fig. 2LT g` v I Lilejparts are' indicated by similar' characters of reference throughout the different figures.H Y f VIn the apparatus illustrated the receptacle l i-s provided with ineens for permittinfg'tlie i entrance' andy eX-it; of objects that are toz be coated, the Object 2` illustrated Withiir the receptacle being a portion of a be'dstead. The airV pipe 3 connects one end of the receptacle l with al fan 4, the other end of the receptacle being connected with thisu fan by `an air pipe' 5,- the'v pipes 3 and 5 virtually iro ed with the top side of a valve casing 7, the bottom side of this casing being connected with the upper end of the measuring pipe 8 whose lower end is connected with the top side of the valve casing 9. The under side of the valve casing 9 is connected with the upper end of the discharge pipe 10 whose lower end is connected ywith the top' side of the valve casing 11. The lower side of this latter valve casing is connected with the receptacle through the intermediation of the pipe 5. Said valve casings and the pipes 8 and 10Vtogether form a combined casing n containing the valve mechanism which is employed in measuring the quantities of sub divided material (illustrated by the dots 12) and controlling the discharge thereof. Said valve casings are desirably similar and the cutovalves 13, 14 and 15 are desirably in the form of disks which turn Within their respective casings that define and guide the disks in their rotation. The valve disks are' iii fixed relation with yeach other, having square holes at their centers through which a square rod 16 passes and which rod fits said square holes. The holes in the valve casiiigs through which the rod 16 passes are similar-so that the rod may be turned and withit carry the valves. The upper end of the rod carries a handle 17 by which the rod may be turned. The valve opening 18 in `disk 13 may be diainetricallyV opposite the valve opening 19in the valve 14. The valve opening 20 may be diametri'cally opposite the valve opening 19 and therefore in alineinent with the valve opening 18. When the valves are in theadjustmeiit illustrated in Fig. 2 the lower end of the measuring pipe 8 is closed by the valve 14 while the upper end of measuring pipe is opened at the valve 13 whereby the powder may enter the measuring pipe from the hopper 6. When the valves are iii the adjustment illustrated in Fig. 4 both of the cutoff valves 13 and 14 are closed so that no more ypowder may enter the measuring pipe and none will be discharged therefrom. When the valves are in the adjustment illustrated in Fig. 5 the cutoff valve 13 is still closed while the valve 14 is opened whereby the quantity of powder measured in the pipe 8 may f'md access to the discharge pipe 10. In order that the powder may enter the receptacle from the discharge pipe 10 the valves are again closedin the adjustment shown in Fig. 2 in which the valve 14 closes the upper end ofthe discharge pipe and the valve 15 opens the lower end of this pipe whereby the powder may enter the receptacle, the valve 14 preventing the eXit of any powder laden air and preventing the passage of air through the measuring pipe 8 and the hopper 6 that would scatter the same upon the exterior of the hopper. By placing the openings 18 and 19 diametrically opposite there is an interval in which both valves 13 and 14 simultaneously close the measuring pipe at both ends and for a similar reason there is also an interval iii which both valves 14 and 15 simultaneously close the discharge pipe. By this arrangement the measuring pipe 8 is completely filled before the contents may be discharged therefrom and subsequently the discharge pipe is completeiy filled before its contents are emptied. Predetermined iiXed quantities of the subdivided material are thus assured entry within the receptacle.

The amount of powder measured by the measuring pipe 8 is adjustably determined by means of the valve 21 and the partition 22. When this valve 21 is thrown to the right it forms a transverse continuationof the partition 22 and as this partition eX- tendsto the valve 14, the space confinedby the partition 22 and valve 21 is cutoff from. the balance of the space within the meas uring pipe so that thisfpart of the space will .not receive the powder.v This arrangement is employed when the object to be coated, or a given run of the apparatus, requires less powder than that which would lill theentire pipe 8. Y
